Several flaws were found in the way SeaMonkey processed certain
malformed JavaScript code. A malicious web page could execute
JavaScript code in such a way that may result in SeaMonkey crashing or
executing arbitrary code as the user running SeaMonkey.
(CVE-2007-0775, CVE-2007-0777)

Several cross-site scripting (XSS) flaws were found in the way
SeaMonkey processed certain malformed web pages. A malicious web page
could display misleading information which may result in a user
unknowingly divulging sensitive information such as a password.
(CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)

A flaw was found in the way SeaMonkey cached web pages on the local
disk. A malicious web page may be able to inject arbitrary HTML into a
browsing session if the user reloads a targeted site. (CVE-2007-0778)

A flaw was found in the way SeaMonkey displayed certain web content. A
malicious web page could generate content which could overlay user
interface elements such as the hostname and security indicators,
tricking a user into thinking they are visiting a different site.
(CVE-2007-0779)

Two flaws were found in the way SeaMonkey displayed blocked popup
windows. If a user can be convinced to open a blocked popup, it is
possible to read arbitrary local files, or conduct an XSS attack
against the user. (CVE-2007-0780, CVE-2007-0800)

Two buffer overflow flaws were found in the Network Security Services
(NSS) code for processing the SSLv2 protocol. Connecting to a
malicious secure web server could cause the execution of arbitrary
code as the user running SeaMonkey. (CVE-2007-0008, CVE-2007-0009)

A flaw was found in the way SeaMonkey handled the 'location.hostname'
value during certain browser domain checks. This flaw could allow a
malicious web site to set domain cookies for an arbitrary site, or
possibly perform an XSS attack. (CVE-2007-0981)

Users of SeaMonkey are advised to upgrade to these erratum packages,
which contain SeaMonkey version 1.0.8 that corrects these issues.
